PZEM-003 DC Voltage Current Frequency Power Energy Consumption Meter Communication Module

  • 【Multifunction】This module is mainly used for measuring DC voltage, current, active power, frequency and energy consumption. The module is without display function, the data is read through the RS485 interface
  • 【Input Power】Comes with built in shunt, the current measure range is 0.01-10A. RS485 interface is passive output, need external connect 5V power supply and the external power supply should >100mA
  • 【UART to RS485 Interface】Physical layer use UART to RS485 communication interface, baud rate is 9600, 8 data bits, 2 stop bit, no parity. When the input test voltage is less than 7V, it must supply 5V independent work voltage through USB port. Do NOT use the USB port bring by your PC to be the independent power supply, otherwise it may damage your PC
  • 【ModbusRTU Protocol】The application layer use the ModbusRTU protocol to communicate, it only supports function codes such as 0x03, 0x04,0x06, 0x41, 0x42, etc. It can display six measurement parameters on the computer when communicate through the software; it can also communicate with the buyer’s own micro controller (the buyer should program by yourself)
  • 【Widely Use】Voltage threshold can be set, divide into high voltage and low voltage threshold, when the measured voltage exceeds the threshold, it can alarm. The high accuracy, better compatibility will make it use widely

This module is mainly used for measuring DC voltage, current, active power, frequency and energy consumption, the module is without display function, the data is read through the RS485 interface.
